Pope Clement X (Latin: Clemens X; 13 July 1590 – 22 July 1676), born Emilio Bonaventura Altieri, was Pope from 29 April 1670 to his death in 1676.

Early life

Emilio Boneventura Altieri was born in Rome in 1590, the son of Lorenzo Altieri and Victoria Delphini, a Venetian lady. His brother was Giambattista Altieri. The Altieri family belonged to the ancient Roman nobility and had enjoyed the highest consideration at Rome for several centuries; they had occasionally contracted alliances with the Colonnas and the Orsinis. During earlier pontificates, Altieri held many important offices and had been entrusted with several delicate missions.

Early work

After finishing his studies, Altieri was named auditor of Giovanni Battista Lancellotti in 1623, in the nunciature of Poland. On his return to Rome, he was named Bishop of Camerino, then governor of Loreto and of all Umbria. Pope Urban VIII (1623–44) gave him charge of the works designed to protect the territory of Ravenna from the unruly Po River.

Pope Innocent X (1644–55) sent him as nuncio to Naples, where he remained for eight years. He is credited with the re-establishment of peace after the stormy days of Masaniello. Pope Alexander VII (1655–67) confided to him a mission to Poland.

Pope Clement IX (1667–69) named him Superintendent of the Papal Exchequer (in charge of the Church's finances), and in 1667 his maestro di camera, and he was made Secretary of the Congregation of Bishops and Regulars. Just before his death, Clement IX made him a Cardinal. He was then about seventy-nine years of age; and Clement IX, when making him a member of the Sacred College, said to him: "You will be our successor."

After the funeral of Pope Clement IX, sixty-two electors entered into conclave on 20 December 1669. Forty-two votes were necessary, and heated discussion prevailed for four months; Giovanni Cardinal Conti was supported by twenty-two votes; Cardinal Rospigliosi, nephew of the late Pope, had thirty, or, as some say, thirty-three, with two at the accesso, so that he needed only seven more votes to gain the tiara. Cardinal Cerri obtained twenty-three votes.

At length the cardinals agreed to resort to the old expedient of electing a cardinal of advanced years, and proposed Cardinal Altieri, almost an octogenarian, whose long life had been spent in the service of the Church, and whom Clement IX, on the eve of his death, had raised to the dignity of the purple. The reason a prelate of such transcendent merits received the cardinalate so late in life seems to have been that he had waived his claims to the elevation in favour of an older brother.

On 29 April 1670, the papacy was offered to him by fifty-nine Cardinals present at the election; only two being against him. He, however, objected because of his age, for he was almost eighty, and exclaimed, "I am too old to bear such a burden." Pointing to Cardinal Brancaccio, Altieri said he was the Cardinal whom they ought to elect. He persisted in refusing, protesting that he no longer had strength or memory; eventually, with tears he accepted, and out of gratitude to his benefactor, by ten years his junior, he assumed the name of Clement X. He was crowned on 11 May.

All but one of the male scions of the Altieri family had chosen the ecclesiastical career. On his accession to the papacy, Clement X, in order to save the Altieri name from extinction, adopted the Paluzzi family, and proposed that one of the Paluzzi should marry Laura Caterina Altieri, the sole heiress of the family. In exchange for adopting the Altieri surname he would make one of the Paluzzi a Cardinal. Following the wedding, which he officiated, he appointed his relative by marriage Cardinal Paluzzi-Altieri, the uncle of Laura's new husband, to the Office of Cardinal Nephew to take on the duties which he was prevented from doing by age. The main activity was to invest the Church's money, and with advancing years gradually entrusted to him the management of affairs, to such an extent that the Romans said he had reserved to himself only the episcopal functions of benedicere et sanctificare, resigning in favour of the Cardinal the administrative duties of regere et gubernare.

On the 8th of June Clement X took possession of St. John Lateran. On 11 June, he confirmed the Minor Observantines in the Holy Land in the privileges and indulgences granted to those who visit the holy places, according to the decree of Popes Alexander VII and Clement IX. In the same month he granted to the prelate-clerks of the chamber the use of the violet-coloured band around their hats.

Like all the pontiffs, Clement X advised the Christian princes to love each other, and to prove it by an entire confidence, by generous measures, and by a prudent and scrupulous conduct. It was especially between Spain and France that the pope desired to witness a renewal of feelings of good understanding.

In 1671, the Pope published an edict by which he declared that a noble might be a merchant without loss of his nobility, provided always that he did not sell by retail.

Canonizations and beatifications

On 12 April 1671, Clement X canonised five new saints:

Clement X confirmed the exemptions granted by Pope Gregory XIII (1572–85) to the German College at Rome in 1671; and then, on 16 October 1672, he ordered the pupils to swear that at the close of their studies they would set out for Germany without a day's delay.

On 13 January 1672, Clement X regulated the formalities to be observed in removing the relics of saints from sacred cemeteries. No one was to remove such relics without the permission of the cardinal-vicar. They were not to be exposed for the veneration of the faithful, unless previously examined by the same cardinal. The principal relics of the martyr – that is to say, the head, the legs, the arms, and the part in which they suffered – were to be exposed only in the churches, and they were not to be given to private persons, but only to princes and high prelates; and even to them but rarely, lest the too great profusion should deprive relics of the respect which they ought to inspire. The Pope decreed severe penalties against all who gave a relic any name but that given by the cardinal-vicar. The pain of excommunication was pronounced against all who should demand any sum whatever for sealed and authentic relics. These decrees, and others made by preceding Popes, were confirmed by Pope Clement XI (1700–21) in 1704. He beatified Pope Pius V (1566–72), Francis Solano, and John of the Cross, all subsequently canonized by Clement XI and Pope Benedict XIII (1724–30).

Clement X, on 24 November 1673, beatified nineteen Martyrs of Gorkum, taken prisoner at Gorcum, the Netherlands, and put to death in Brielle on 9 July 1572, in hatred of the Catholic faith, the primacy of the Pope, the Roman Church, and the Holy Sacrament of the Eucharist. Of the nineteen Gorcum martyrs, eleven were Franciscan priests; Peter Ascanius and Cornelius Vican, laymen; one Dominican, two Premonstratensian monks, a regular canon of Saint Augustine, and four secular parish priests.

Fernando III called El Santo (the Saint), (1198/1199 – 30 May 1252) was a king of Castile (1217–1252) and Leon (1230–1252). He was the son of Alfonso IX and Berenguela of Castile, daughter of Alfonso VIII. In 1231 he united Castile and León permanently. Fernando was canonized by Pope Clement X in 1671. Several places named San Fernando were founded across the Spanish Empire.

Clement X also had declared Venerable one of the famous Spanish mystics, Sister María de Jesús de Ágreda.

In 1676, Gianlorenzo Bernini scculpted one of his final statues, a bust of Clement X.

Foreign affairs

Clement X, seeing the results of the apostolic labours of the early French missionaries in see at Quebec, the bishop to depend directly on the Holy See; this provision would later secure its permanence after Quebec passed into the hands of England. The first bishop was Monsignor Francois de Montmorency-Laval.

In 1673, there arrived at Rome ambassadors from the Grand Duke of John Sobieski of Poland in their fight against the Turkish invaders. But Paul Menesius, a Scotsman, who was the ambassador, could not obtain the grant or sanction of that title, though he was received with great magnificence and had many precious gifts to carry back to his master. The Grand Duke of Muscovy did not profess the Catholic faith in such a manner as to give any assurance of his intentions, and the King of Poland had looked upon the embassy with displeasure.

Local administration

Meantime Rome had reason to fear trouble. Cardinal Altieri, who was at the head of the government, determined to increase the revenues, and he established a new tax of three percent upon all merchandise entering the city, including even goods for cardinals and ambassadors. Although the government complained that ambassadors had abused their privilege, the diplomatic corps showed discontent that they were not expressly exempted in the new tax law.

Another edict confirmed the first, and ordered the confiscation without distinction of all goods that did not pay the new tax. The cardinals at first complained, though with moderation. But the ambassadors didn't speak Clement X's language.

The Cardinal nephew maintained that Clement X, within his own State, might make what rules he pleased. Then the ambassadors of the empire, of France, Spain, and Venice, sent their secretaries to demand an audience of the Pope. The chief chamberlain replied that the Pope was engaged that day. And for four days in succession the chamberlain gave the same answer to the same applicants. Clement X, learning at length what had occurred, declared that he had given no such order. The ambassadors then sent their secretaries to ask an audience of Cardinal Altieri. He not only refused to admit them, but closed his doors and increased the guard at the pontifical palace, so that the offence could go no further. Subsequently the Cardinal nephew wrote to the nuncios who resided in the courts of Europe, stating that the excesses committed by the ambassadors had induced the pope to publish the edict. The ambassadors, on the contrary, assured their sovereigns that the accusation was a pretext.

The conflict lasted for more than a year; and Clement X, who loved peace, at length referred the matter to a congregation. Some time after, Cardinal Altieri declared that he had not intended to comprise the ambassadors among those for whom the edict was intended, and that the pope had never contemplated subjecting them to it.

Queen Christina of Sweden, who had become a Catholic and moved to Rome in December 1655, made Clement X prohibit the custom of chasing Jews through the streets during the carnival. In 1686 she issued a declaration that Roman Jews stood under her protection, signed la Regina – the queen.[1]


In the year 1675 Clement X celebrated the fourteenth jubilee of the holy year. Notwithstanding his age, he visited the churches, regretting that the gout prevented him from making that holy visit more than five times. He went twelve times to Trinity hospital to wash the feet of the pilgrims, and after the ceremony gave them liberal alms. However, Rome made some complaints, and said that, though Clement X was Pope in name, Cardinal Altieri was Pope in fact.


Tomb of Clement X, St. Peter's Basilica

On the 22 July 1676, the agonies of the gout became so violent that Clement X died under them. He was eighty-six years old, and had governed the Church six years, two months, and twenty-four days. His tomb is in St. Peter's Basilica.

Other accomplishments

He laboured to preserve the peace of Europe even though he was menaced by the ambition of Louis XIV of France (1643–1715), an imperious monarch over ecclesiastical matters (the struggle concerned the régale, or revenues of vacant dioceses and abbeys, which resulted in continued tension with France). He decorated the bridge of Sant'Angelo with the ten statues of angels in Carrara marble still to be seen there.

To Pope Clement X we owe the two beautiful fountains which adorn the Piazza of St. Peter's church near the tribune, where a monument has been erected to his memory. During his papacy, the Palazzo Altieri in central Rome was refurbished.

Clement X appointed Francesco Lorenzo Brancati di Lauria head of the Vatican library.
